I made $900 donation to a charity last October. My company matched $900 as well. But the charity didn't really receive the fund until January this year. My questions:
1. Should I report this donation on my 2020 return or 2021? which date should be used-- the date I made the donation or the date the charity receives it?
2. How much should I be reporting? $900 or $1800? The receive charity sent me is $1800.
Thank you all!
