"and paid my 2021 taxes expecting it to be processed before the extended filing deadline of October 17th, 2022"
This is the correct action.
Similarly, file 2021 Form 1040 assuming your 1040-X has been processed.
If you want to slow down your 2021 Form 1040, file it on paper via US Mail. That will do it.
You will get behind 5.6 million currently waiting paper returns already ahead of you.
If you are due a refund, this is not advisable.
