I asked the exact same question but likely not as clearly as you did! My daughters received the refunds and deposited them, and my plan was to do the same- reduce the 529 withdrawal in 2020 by the amount of the refund. I was past the 60 days to redeposit when I first read about this in Kiplinger magazine, and my daughter already deposited the funds. I have this situation with 2 children and 2 529 plans. They both will be filing a tax return and could report the refunds as taxable income, but that doesn't seem fair when I can just reduce the 529 withdrawal this year. Did you find any additional information on this? I know your question was a couple of months ago.
