The system is saying I cannot file my California tax return electronically due to withholding from a source other than W2, 593, etc AFTER I entered the Form 593.

I entered a Form 593 for Real Estate Witholding to my California Tax Return. Once I did that, they system says I cannot file my California Tax Return electronically because "the return has withholding from a source other than Forms W2, W2G, 1099R, 1099G, 1099INT, 1099DIV, 1099B, 1099MISC, 52B and 593".
