"Consult a CPA or Tax Attorney. They can tell you what to do legally."
Well, the OP did say: "I also can’t afford to hire a tax professional since it’s hundreds of dollars."
To the OP: I went to H&R Block earlier this year to do my 2021 tax returns. They charged me less than $100.00. I went there knowing I'd have to pay them, because I had what I thought were very unique and special problems. (They were not so unique after all.)
Also, the AARP (even though you're probably nowhere near old enough to be a member!) -- the AARP has free tax preparation centers throughout the country prior to tax filing date. I had my taxes done by them for about five years before the pandemic hit. They usually start preparing tax returns in March or maybe earlier, for the April 15 deadline. Granted, the intent of AARP is to help senior citizens, but I have seen college-age people in those centers as well. I don't think they're allowed to turn anybody away simply because of age.
There have been so many, many posts on this subject of taxation of sales from eBay and the fact that eBay is now required (federal laws, you know) to send sellers a 1099K form when their sales surpass $600.00 during the calendar year.
Over the years, some posters have given links to websites or at least referred to email addresses that focus on taxation of income for online sellers -- like those of us who try to sell on eBay. Unfortunately, I haven't written them down . . . . I hope one or two of those of those posters will come along and post the links again. I think a lot of us can use all the help we can get.
