The shared rent payments are not taxable. You don't put the payments on your tax return unless you get a Form 1099-K from Cash App. You should not get a 1099-K because the payments are personal, and below the amount that Cash App is required to report. But if you do get a 1099-K, come back here and someone will tell you how to handle it. For now, don't enter them in TurboTax at all.
