Get your taxes done using TurboTax

Go back to the exact same account with the exact same user ID you used, and you will probably have to click on Add a State to get back in to the return.  You will not really be adding a state, but that will let you back in to work on your return. Did you enter the payment you made into your tax return?  Go to Federal>Deductions and Credits>Estimates and Other Taxes Paid>Other Income Taxes  This will show up on line 70 of your Form 1040
The very last day to e-file a 2017 return is October 15, 2018.  After that, e-filing for 2017 will close down permanently, and 2017 returns will have to be printed, signed and mailed.  It is recommended that you get it e-filed before that deadline if you can, “just in case” of last minute problems.
