Stuck in a loop with Royalties

I have a modest amount of Royalties from being a book co-author

I enter them as every year, but this year Turbotax gets stuck in a loop. When I am ready to file, it does the final review and I get this screen from which, no matter what I do or write in the white box next to Schedule C, it always goes back there.

 

Any help is greatly appreciated!
