Amazon Collected Sales Tax Reported as Gross Income on 1099K - Where to Report on Federal Taxes

Due to the SCOTUS ruling, many states began making Amazon charge sales taxes in 2019 - on everything sold via Amazon (also Ebay, etc). Those of us who are 3rd party sellers on Amazon saw Amazon charge our customers sales taxes, collect those individual sales taxes, pay the individual sales taxes collected to each state - and then report the sales taxes collected in our gross sales on out 1099-K. They reported the sales tax collected as an expense on our statements, but still included it in gross sales to the IRS. So...  Anyone who sold on Amazon/Ebay/etc in 2019 and going forward are showing the sales taxes collected in our Gross Transaction amount in Box 1 on our 1099-K...   Where do we report these taxes collected to lessen our Gross Sales, on our Federal Taxes,  by this amount? (In the past Sales Tax was only a State Tax Reporting Issue - Now it is Federal due to this).
