I have filed 2020 taxes received my refund. However, I left out income that reduced my refund by $300. Do I need to file 1040-X or will the IRS correct it automatically?
You will have to file an amended 2020 tax return to make the changes to the original 2020 tax return.
See this TurboTax support FAQ on amending a tax return originally completed and filed using the 2020 TurboTax editions - https://ttlc.intuit.com/community/amending/help/how-do-i-amend-my-return/01/27439
The IRS Form 1040-X for amending a 2020 tax return is scheduled to be available on 03/26/2021 (subject to change)
