I was the first H&R Block client who claimed eBay income (1997 or 1998) per H&R Block.
They made numerous calls while I was there checking out the specifics of my spread sheets showing costs of goods, S/H and selling prices (I did not charge sales tax for in-state sales as that was not a requirement @ the time).
I pointed out to them that I had not taken out a DBA, which I assumed was required to itemize profit/loss, but they said that it was not needed (it was, IMO but as they were willing to sign off on it I went forward with them).
This is the only time I have ever fudged anything in my life and it still haunts me.
