I want to efile a 2nd 1040x for 2021. i am using the first 1040x and making the change. The first 1040x

merely was requesting the refund to be applied to 2022 estimates. It was filed one day after original 1040 efiled.

Now I can't efile the new 1040x because IT has already been efiled. So, I need a 2nd 1040x to be processed but I don't know how to do a 2nd 1040x  that can be efiled on its own. I can call proseries

but I thought I would ask here.

Thanks
