Business & farm

In the top right hand corner of turbo tax, in the blue strip, there are 3 icons: forms, flags, notifications. Clicking "forms" toggles you back & forth between the forms view & step-by-step view.  My suggestion is to go into the forms view where you can look at the underlying forms & worksheets filled in when you go through the step-by-step method.  The list of forms down the left hand side are all the forms that have been "opened" in the process of doing your return. There will be a red exclamation mark ! next to the form that has the error. I find it is usually quicker/easier for me to locate what is causing the issue that way as the worksheets show the steps leading to the number entered on the tax return itself.  Hope this helps you fix your issue
