Can you help??I filed my 2021 amend and it was accepted by the IRS. it has been over 3 months and I have yet to revive my return. What can I do to fix this ?

Sorry returns are taking over 6 months this year, especially amended returns.   You have to be patient and keep waiting.  

You have to wait since amended returns take 6 months or more to process. 

Amended returns currently take eleven months or more to be processed.

And if you filed the amended return before the original return was fully processed this may delay both returns so all you can do is wait and check the IRS site once a week ... https://www.irs.gov/filing/wheres-my-amended-return
