According to the instructions from TurboTax support at this link https://ttlc.intuit.com/questions/2840416-can-i-set-up-a-payment-plan-for-my-taxes once you get to the "how would you like to file your taxes" there is supposed to be an option to set up a payment plan if you owe money. I followed the instructions and no option appeared. Where do I find this option? Or is it no longer available in 2017 TurboTax Deluxe software?
This option is still available for 2017. You should see "I want to request an installment plan" as an option when you go through the File screens if you have a federal balance due. (It doesn't matter which version of TurboTax you are using.) Please click the ".png" file below to see how this screen looks in TurboTax Online.
If you only owe taxes to your state, you won't be able to set up an installment plan through TurboTax. Try contacting your state Department of Revenue to make arrangements if you cannot pay the balance in full.
