Why was a form 8962 not included in my return. i filled it out and completed it

The IRS Form 8962, Premium Tax Credit is not a form that is completed by the user of the software.  The TurboTax program will automatically generate the 8962 but only after the user has entered the Form 1095-A that they received for Marketplace Insurance in the Health Insurance section of the program.  If a Form 1095-A was not entered then a Form 8962 will not be included with the tax return.

If you received a notice from the IRS concerning a Form 8962 follow this procedure -

1. Sign into your account with the same login you used when you filed your 2018 return.
