So you had about 80k of ebay fees, right?

By inventory, is that the cost of the items you sold? Or how much inventory you bought, even what didn’t sell?

Was the home office used exclusively for business?

The driving, what kind of driving was it?

Not possible to answer without knowing where you are and how much other income you have. Sounds like you have done pretty good accounting though, that’s a really good start.

Side note- did you pay 80K in ebay fees? That seems really high. I pay them less than that on significantly higher gross.

Don’t forget your printer, ink, shipping labels, shipping supplies also equipment like shelfs, bins, sorting/organizing supplies.
