After you file

@DawnC  I don't think so if the poster is asking about the retroactive credits for 2018.

TurboTax has not released any 2018 software updates for amending 2018 since September 2019.

 

The revised 2018 Schedule 1 on the IRS website is still in the draft state.   The currently available Schedule 1 does not support the tuition and fees deduction on line 33.  No telling when the form might become final with the current IRS partial shutdown.   After it becomes final it usually takes a month or more before the form specifications for tax software providers are released by the IRS.
