Check This Entry Sch SE-T: Max deferral line 18 is too large. Max deferral line 18 I don't know what this means and I'm not sure why I am getting this error.

Leave this cell blank.

The amount for Line 18 of Sch SE-T Part III is an allocation of income earned between March 27 and December 31, 2020. This is needed to properly calculate deferring 50% of self-employment taxes.

If the program is not accepting No, I do not wish to defer any self-employment taxes, but needs to update, it may be from the following scenario:

• While the return was in a balance due, the tax return was eligible for the Cares Act self-employment tax deferral option. This section was completed.
• However, as more details were entered and the results changed to a refund, the SE tax deferral option was no longer available. 

As initially indicated, to manually update your program, at the check this entry, the best solution is to enter nothing--leave the response blank. Run the review again to confirm the issue is resolved.
