I already got accepted yesterday but I added another w2 today an my refund amount changed but it still says previous amount on my home page

Delete the second W-2 you entered after filing the 2019 tax return.

If the tax return is accepted then you will have to amend the tax return to make your changes. An amended tax return, Form 1040X, 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
