I amended and it's showing xxxxx where my checking account information is supposed to be, unlike the original where it has the numbers. Does that mean a paper check?

Are you referring to Lines 31 and 32 on the Form 1040-X which show the bank routing and account numbers for a direct deposit?  If so, those numbers will not be visible on the Form 1040-X until it has been e-filed and accepted by the IRS.  Assuming you are referring to amending a 2023 tax return.

It was 2023. It's been accepted I have my 846 code but here the lines are showing all XXX still but wmr says it's being sent to my bank. I just want to know which I'm getting cuz I have to move for work soon and need to know where and how I'm getting it

The IRS will mail a printed check to the address you provided on the amendment.  There will be no direct deposit.
