You will need to amend your tax return and file it again. You can do this in TurboTax.
You might need to file an amended return if any of the following are true:
Before you amend your return, here are three things you need to know.
First, make sure you got your refund or paid your taxes due from the originally filed return; you want to make sure the government doesn’t get confused with your money, so the original return needs to be all squared away before you amend.
Second, print a copy of your original return and have it right by your side when you start to amend in TurboTax. Trust us; this is really important.
Third, you can amend this year’s return only with this year’s version of TurboTax. If you want to amend your return from a prior year, use that year’s version of TurboTax.
Remember before you amend: amend only if you need to make a change on a return you have already filed. Wait until you got your refund or paid your taxes. Have a copy of your original return at your side before you start. And be sure you use the correct year’s version of TurboTax.
