I need assistance with admending taxes from 2021 and filing my 2024 taxes too

Wait until your original return has been fully processed before you amend, and make sure you have saved a pdf of the original return before you amend. (If you do not save it as a pdf, the amended return will overwrite the original, and the original will be lost forever)

Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.
