The problem is that Turbo Tax will not accept multiple 1095-A forms with the same marketplace ID (it asks for the last 15 digits/characters). If you try to combine the data from the different 1095-A forms to cover the entire year (as Form 8962 does), TurboTax will NOT fill out the monthly calculations on Form 8962. To get TurboTax to fill out the monthly details, I entered 14 digits as the marketplace ID for one of my 1095-A forms. It would have been helpful if Turbo Tax stated that this was an option.
I found all this out after I e-filed but then got a letter from the IRS requesting a completed Form 8962 be mailed in; my refund is now delayed 6-8 weeks.
