It looks like Intuit/Turbo Tax did an update to their software. I am using the Mac desktop version of Turbo Tax Home & Business. I found the way, I think, to offset my 1099-K which was used to solely move money around my various sportsbooks.
Go to Personal -> Personal Income -> Other Common Income -> Income from Form 1099-K.
If it is all from moving money around gambling sites and none of it was actual income, select the last option at the bottom, "Other (can include any taxable income not reported elsewhere on your return) OR if the entire amount is incorrect" and select Continue.
Input all of the 1099-K information as it is on your 1099-K otherwise the IRS will flag your return, but then in Turbo Tax under where the information for box 4 is, check the box where it says, "This amount in box 1a is incorrect". Then select, "Box 1a is overstated or contains personal use amounts." From there you can enter the amount of box 1a that should not have been reported to you or is for personal use. Make sure the amount you enter that is personal is less than the 1099-K box 1a amount. In other words, remove the cents or make it less by $1.00. Mine was exactly as in box 1a and Turbo Tax kept saying there was an error as the amount that is personal cannot be greater than what is in box 1a. It is a coding issue, but easier to just manually correct it by $1.00.
Make sure you also enter all information into Turbo Tax that is in boxes 6 to 8 of the 1099-K as well.
NOTE: I am not a CPA, financial planner, or advisor so please do your own research, but this is what I plan on doing.
