What all forms do i mail in with federal tax payment? just the 1040 with w2 or all the schedules too?

Did you efile your return?

It is possible to e-file the tax return and mail in the tax payment. 

If that is what you want to do, make sure your social security number is on your payment (check or money order) 

 

If you are mailing in your tax return and NOT e-filing, TurboTax gives you instructions when you print out your return. 

Include your W-2 and any other tax forms. 

Schedules also. 

Put them in order by the number on the forms/schedule starting with the 1040. 

 

The program should tell you where to mail based on the state in which you live.
