Paid for an Extension but didn’t owe

Paid for extention (didn't owe) then had to pay again to file. Is this 🤔 right? Feels scammy. I did MOST of the work...as a RealEstate Pro thought I would get to use up to $1M Sec 179 deductible for my rental but was limited to -25k.  Very few actual professionals to help with 179 allocation questions.  Feeling robɓed.  Finally filed now.  Can anyone recommend a better software 🤔 company for 2024?
