Can't delete MN schedule M15 or the underpayment statement in desktop version

I am using TT desktop for MN taxes. I wanted to see if the alternate calculation for penalties on underpayment would change the penalty amount. However, I no longer want to use the regular method on the MN schedule M15 or the underpayment statement. I want to use the default, short method.

I go into View, Forms and try to delete either or both forms. It won't let me delete them, which means I can't file electronically. I went back and looked at the place where it allows you to trying the alternate calculation and, in small print, they put a message "if you use it, you can't file electronically".

I just want to delete the forms and use the default method. Is there any way to do that?
