State tax filing

On the Colorado return review, Form DR1366 line 88 should be 0 and is 0, but  the review says there is a problem that needs to be fixed before filing.

I have tried the fix that BillM223, turbo tax expert, suggested and it does not work.  Another turbo tax expert said if this doesn't fix the problem that the CO return should be printed and mailed.  Colorado says if you are filing this form the return needs to be electronically filed. 

So, can this Colorado return be mailed rather than electronically filed??
