Per the IRS:
Don’t amend for math errors or missing forms. Taxpayers generally don’t need to file an amended return to correct math errors on their original return. The IRS may correct math or clerical errors on a return and may accept it even if the taxpayer forgot to attach certain tax forms or schedules. The IRS will mail a letter to the taxpayer, if necessary, requesting additional information.
