Made a mistake- wasn’t paying attention

So I THOUGHT I entered  both w2 on my return . Apparently I didn’t . Both jobs I made around 7850$ each . I also got the tax credit for my health insurance . I used the full available credit for that . I thought I would make around 2400$ for the previous tax year but it wasn’t even 16000$$. I entered my 1095, and only one w2.. it said my refund would be around 1890$ , but then I quickly saw I forgot the second w2, but I just got a notification that the IRS accepted my return . According to several tax estimators adding my second w2 will make my refund around 500$ lower .. I wasn’t able to enter the 1095 info on the estimator so idk if that effects anything . I don’t know what will happen next .. I  am beating myself up .. does anyone have any clue what will happen next ?( and yes I will file an amended return !!)
