"It was convenient to do it at home, because as options for deductions were presented - I was able to dig through home files to find receipts and exact figures. If I had gone to a tax preparer, I would have had to go home, find the items, hope I had gathered everything and that something else would not be required if more opportunities arose - and then would have had to schedule a time, during the tax preparer's hours to deliver and discuss the supporting documentation.
But, the Capital Gains/losses 1040 area had a requirement to fill out a wksht. Yet, it allowed me to overwrite on the 1040. Then when went to clear - it was a painful field by field check/uncheck overwrite process."
