to fix the 179 issue you have to go into the 4562 for each activity. there should be lines for total 179 and right below that allowable amount, you must enter 0 (zero) for allowable amount or in step by step mode in final review enter 0 as allowable amount. you should then get a message the 179 issue has been fixed.
