I finished my return but can't file because of the message stating "schedule M1W 1 Line 2- income must be entered". However, when I look back at the actual M1W form, I can see an entry on line 2 (which equals the totals of a1 and a2 above). I see no error but am blocked from e-filing my return (unless I print and mail).
I've followed advice to try clearing my cache and using a different browser without success.
