To enter your Form 1095-A -
Or enter 1095-a in the Search box located in the upper right of the program screen. Click on Jump to 1095-a
BUT - If you received a letter from the IRS requesting a Form 8962, you DO NOT amend the 2019 tax return. Cancel the amendment by clicking on Cancel Amend
See this TurboTax support FAQ for the Form 8962 and the Form 1095-A as requested by the IRS for 2019 - https://ttlc.intuit.com/community/health-care/help/the-irs-is-requesting-form-8962/01/27409
I have this same issue. I was instructed to fill out the form online and then print it and fax to IRS along with the 1095a. I didn't get a letter from the IRS though. I found this out by calling the IRS myself. It's gonna delay the refund I was told (up to 8 weeks). Turbo Tax will never be used again in my house. This is ridiculous and nobody on Turbo Tax's end seems to care.
If you click on the little bubble that says live help an agent with turbo tax will step you through filling out the 8962 form. But they are mostly copying and pasting from some sort of help document so don't ask any hard questions 🙂
I was also given this fax number for when your ready to send in the forms. [phone number removed]
Hope this helps
