Retirement tax questions

Thank you for the response. Since this approach requires itemizing, I followed the method below instead (also from TurboTax Community). Is this another valid way to offset 1099-K gambling payments?

 

  1. From the left menu, go to Federal and select the first tab, Wages & Income
  2. Add more income by scrolling down to the last option, Less Common Income, and Show more
  3. Scroll down to the last option, Miscellaneous Income, 1099-A, 1099-C and Start
  4. Choose the last option, Other reportable income and Start and Yes
  5. Enter the applicable description and amount and Continue
    • First, enter Form 1099-K as received. It is essential that the full amount be entered.
      • For a description, include Form 1099-K and Personal Property Sales
    • Next, enter an adjustment to reflect the cost of these items as an offsetting, negative amount up to the amount of the income.
      • For the cost description, include Form 1099-K and Cost of Personal Property 
      • In other words, if the goods cost you $100 and Form 1099-K was for $10 in sales, the maximum cost allowable would be $10.
