if your return is still processing you should not file an amended return at this time.
what year are we talking about? you could not have filed a 2024 return because March has not happened yet.
if you are asking about your 2023 return which you filed in March 2024, you should contact the iRS. It normally shouldn't take almost a year to process. This could mean the IRS may have found something wrong with your return and now a human is probably reviewing it. changes could be made which means any amended return you file now, might need to be amended again to reflect IRS changes.
