If you amended your return, you will need to print and mail your forms to the IRS. The IRS does not allow amended returns to be efiled. It takes 8-12 weeks for the IRS to process an amended return

After you have printed and mailed your amended return to the IRS, you can track the status of the return using this tool (please wait three weeks after amending before checking):  https://www.irs.gov/filing/individuals/amended-returns-form-1040-x/wheres-my-amended-return-1
