Thank you for clarifying the impact on SE tax.

Regarding the 1065 M-1 question -

I have followed the instructions for entering the ERC information for amending a 1065. However, unlike amending a 1120S, the ERC credit amount didn't automatically appear as an adjustment on the M-1. I had to manually enter the adjustment.

Is there a reason PS isn't treating the ERC adjustment the same? Or am I missing a step somewhere?

Thank you.
