I had a new client in the opposite sense.  I spread her 1/3 payment just to give her an idea of what she was looking at as far as tax liability.  I told her this may take some time for the 8915E or 8915F (I am still unsure what we are waiting for).  She came and picked up her papers and told me I was taking too long to complete the return.  Someone gave an explanation on how to fix this but it was dated June 2021.  If it is already acceptable to send in the 1/3 payment returns in an acceptable manner please tell me.  Thank you.
