Interesting situation.
--It sounds like you filed your 2018 return last night, is that correct? If yes, did you use the 2019 version of TurboTax to file? If yes again, that is a real problem where you need to contact the IRS and State revenue departments to ask for guidance, because as you may have already guessed it will look like you filed twice for 2019.
--If on the other hand you used the 2018 TurboTax to file your 2018 tax returns, then just used the 2019 TurboTax to file your 2019 return.
