I realized my mistake right after I filed and the government accepted my return. I was told that if they find a discrepancy between my entry and the ones provided by the investment institution which also reports to the government, they'd fix it and refund me. I received the refund check in the mail but it was about $120. If I correct my mistake in turbo tax, the difference is actually that I overpaid by $2,000. I have not yet cashed the check but I don't know how to go about amending my return since they'd already sent the check. If I send in an amendment will whoever reviews it see that there was a mistake and the total I overpaid was more than the $120 they sent to me? Thank you in advance for any advice!
