Retirement tax questions

I received a Form 1099K from Paypal, Inc in relation to sales I made on eBay in 2020.   My sales were only $2,900 and my total transactions were 137.   I live in Massachusetts.   Will this info be reported to the IRS and do I have to report it on my 1040 this year or do I have just have to report it to Massachusetts?   Can I deduct shipping expenses, state tax paid and fees if I do have to report it?   Thanks for your time.
