Your post is confusing ... did you get the original refunds yet ? You should not amend anything until you have the payments in hand.
Now what did you change in the amendment process ? Did you try to change the taxable unemployment ?
I have not received the refund yet but assume it is being processed since it was originally approved. I was supposed to file as a dependent under my mom but didn't. It messed up her taxes and I probably won't get the payment until after tax season is over since I requested the check to be mailed.
Ok ... mom MUST mail in her return even if you amend yours ... she can do so NOW.
Then when you get the original refund AND the amended program is operational you can amend your return. It is possible that amending will not change anything especially if your income is under $12,400 and you did not get the stimulus credit on line 30 of the form 1040 but you must send in the amendment eventually. Make sure to undo any changes on your return BEFORE you start the amendment process.
