How to file in an extra state in 2018?

[jdg33]

I need to file in NY for 2018 due to income earned in NY.  Don't owe taxes but have to file per NY- can this be done using TurboTax?

You would need to install the 2018 TurboTax to a MAC or Windows desktop, import your original return, and then purchase New York state.

I NEED TO PREPARE A PAST YEAR STATE RETURN

If you prepared a 2018 federal return using TurboTax you can also prepare a state return.  Information flows from the federal return to the state return, so you cannot prepare a "stand alone" state return.  And for 2018, you have to use downloaded desktop software on a full PC or Mac.  You cannot use online software for any 2018 return.  Access your 2018 federal return using exactly the same account and user ID and then add the state and prepare it.  You will have to mail the state return.  It cannot be e-filed.  If that sounds like too much aggravation and cost, then get the paper form for the 2018 state return and prepare it by hand.  You will need a copy of your 2018 federal return to look at and get information from.

Of you can get the forms and instructions from the NY website and complete them manually...
