"In other words the grant comes in , the expenses reduce the grant to zero and those expenses not longer reduce SE revenue" "So, now the revenue subject to SE...."

That is exactly the logic I used to complete the  2020 tax return.  

I stated this in my thread responses of 2/20/21 and 03/03/2021, (and mentioned in a thread from qbteachmt), thus I  marked it as "solved". 

And, I am keeping my eye on this topic. If anything changes my fat fingers will be tapping away on an Amendment.  

I thank everyone for their input.
