I would do a pdf attachment. From the instructions for Form 4797
Section 1244 (Small Business) Stock
Individuals report ordinary losses from the sale or exchange (including worthlessness) of section 1244 (small business) stock on line 10.
The maximum amount that may be treated as an ordinary loss on Form 4797 is $50,000 ($100,000 if married filing jointly). Special rules may limit the amount of your ordinary loss if (a) you received section 1244 stock in exchange for property with a basis in excess of its FMV or (b) your stock basis increased because of contributions to capital or otherwise. See Pub. 550 for more details, including information on what is section 1244 (small business) stock.
Attach a computation of the loss from the sale or exchange of section 1244 property. On line 10, enter "Losses on Section 1244 (Small Business Stock)," in column (a), and enter the allowable loss in column (g). Report on Schedule D losses in excess of the maximum amount that may be treated as an ordinary loss (and all gains) from the sale or exchange of section 1244 stock.
Keep adequate records to distinguish section 1244 stock from any other stock owned in the same corporation.
People come to Accountants Community for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:
Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
