A couple of points :
1) amend the 2021 return first ... download the 2021 program & .taxfile from the online system then transfer the amended .taxfile into the 2022 program.
2) you will need the AGI from the original return to efile the 2022 return so be aware that you need that figure not the amended AGI ... from the online system save a PDF of the original return so you have that info
