I electronically filed a 1040 return without the required PPP statement for the taxpayer's Sch C.  Client had 1st PPP in 2020 and had profit in 2020.  Basis is not an issue.  Any of the three options would have been fine to choose.

Do I need to be concerned about fixing this?  If so, I am thinking I would need to file an amended return to attach the statement unless there are other options.

Thanks in advance!
