Well, that is enough to increase your refund or reduce your taxes owed by about $200, depending on your tax bracket. The choice is yours.
If the tax return is accepted then you will have to amend the tax return to make your changes. An amended tax, Form 1040X, return can only be printed, signed, dated and mailed by you to the IRS, it cannot be e-filed. The IRS will take up to 4 months to process the amended tax return. Wait until you have received the tax refund or the taxes owed have been paid and processed by the IRS before amending the tax return.
On the Tax Home web page when the the Form 1040X for amending a 2019 tax return becomes available there will be a link - Amend (change) return
