MyBlock - Overtime

Can someone help me figure out where my overtime pay goes? I have a W2 and am trying to input the info onto the app.

I am at "Now Tell Us About This W2"

At the bottom of Boxes 1-11 I selected "some of my wages were overtime."

I see the box 14, where my OT code is. App says not to put it there, so I don't.

I see nowhere to put It.
