I am having the same problem of Line 18 needing to be filled out. It is blank. When I was asked the question did I want to refer I originally put no. and I got the error in review that line 18 needs to be filled out. So I went back and said yes as suggested and it tells me that I am not eligible to defer since I am getting a refund. When going through the review again. I still get the error that Line 18 needs to be filled out. What should I do. How do I get past this error?
Thanks,
