No, the basis is not the issue. You have negative amounts in the "Sales Proceeds" column on your 1099-B from Robinhood Securities. The Federal return allowed your e-file with this information, but MA will not. If your 1099-B forms are correctly reported (as I assume they are since there are so many line items, I'm guessing you imported your info) then you will need to print and mail your MA return.
I'm glad I've been able to help you out!
