Where do I file my Arizona state return?

I assume you are asking where to mail your Arizona tax return. If so, you can find the list of mailing address for the Arizona Department of Revenue here: http://bit.ly/2HpxLWD.

Otherwise, if you are looking for where to file your Arizona state tax return with the TurboTax program, you can do so through the State Taxes tab on your software.

I WAS going to mail them...but...I can pay them online -- so HOW do i do that?
