Deductions & credits

I have the opposite problem. Here's my question: 

I want my stimulus to be based on 2020 return, not 2019 (because the higher income that year would disqualify me).  On 3/11/21 my 2020 returns were e-filed and "accepted".  Will that be enough time for IRS to process before the stimulus direct deposits are issued?  If not, is there a way to appeal it?
