I have a client in South Carolina which has a Solar Energy Credit. This is the 3rd year  the client has had it and still has a carryover. When I try to attach the Schedule TC-38 (which I have done in the past), I get a error message "Returns with a Solar Energy or Small Hydropower Credit (Schedule TV-38) cannot be e-filed for tax year 2020." ProSeries does not support this information to be filed electronically. The state return has to be paper filed by mail.

Is this being worked on or is a paper file the only solution?
