2 non-dependent children included on 1095-A; one is covered Jan-Aug, the other Jan-December and the taxpayer wants to allocate 100% of the premium and APTC to themselves. I'm having difficulty with the data entry and keep getting a critical diagnostic - 1095-A #1: Only one set of percentages is allowed per month for the Shared Policy Allocation entries. Multiple entries are provided for each policy so that each month or period of months during the term of the policy may have a different allocation percentage. However, for each month or period of months, only one allocation percentage should be present for that policy. Allocations amongst more than two persons or tax households need to be handled in accordance with the instructions in Publication 974. Within those instructions are worksheets to determine the percentage to enter and the SSN to use in the allocation.
