I'm not eligible for self employment tax deferral, because i'm already getting a refund, yet it won't let me e-file. The error I'm being asked to fix: "Line 11 is too large when I enter 0". Won't allow me to enter 0 on Schedule 3 line 12e.

To get rid of the error, don't enter anything on line 11. When the error comes up in Smart Check, delete the zero (or whatever is there) and leave the box empty. Schedule 3 line 12e will be blank, or Schedule 3 will be omitted entirely if there are no other entries on it.

Thank you! it worked!
