Well since you did not amend the 2018 return yet to correct the errors and confirm the IRS changes then wait until the 2019 ONLINE program goes live sometime this week and use the free amendment program to make the changes BEFORE you start the 2019 return ... this way you can transfer the updated tax file into the 2019 program.
