@taxes96786  The OP asked a legitimate question, received enough information, and made a decision, and marked the post solved. That should have ended the conversation.

Not everything is contained in Pub 17. There are at least 3 others that give direction here and you can always delve into the code if you want to split hairs. 

I remember when one of the most prolific and helpful contributors here started by asking questions just like this OP. If you don’t have something constructive to offer then don’t waste your time.
