Form 5695 Energy Tax Credit 2018

The TurboTax program for 2019 was updated to allow me to get the window credit.  I installed a qualifying door in 2018 that the credit was not given because the credit was not available.  I have tried to amend the 2018 return but it still does not give me the credit.  Do I wait for the program to update, file amended return manually or put it in as a carryover to 2019?
