If I qualified for a PHEV tax credit in Deductions and Credits, what paperwork/documentation is required and how how do I attach it to my electronic income tax filing?
You simply need to file Form 8936 with your return, either on paper or electronically. No additional documentation is required for your federal return.
If you completed the 8936 in your TurboTax program, it should've been electronically transmitted with your return. If you go to "Forms" mode in TT, can you not see Form 8936?
