I have not been able to open the tax year 2025 Turbo Tax charitable deductions section yet; Turbo Tax says it is still under construction. But reviewing IRS 2025 Form 8283, it looks essentially the same as 2024 for donations of clothes and household items where the individual item (or group of similar items, as the Form says) have a fair market value of less than $500.00 If your prior donations were below this level, and your current donations are above this level, that may be the reason Turbo Tax is asking about purchase price, etc. Form 8283 requires the purchase price for items valued above $500; this is not new. So what could be driving all this is not Turbo Tax itself (or the IRS) but the size of your donations.
