How do I report a large refund from a 501c3?

I donated over $200k to a 501c3 in 2019 to help it purchase new facilities. 

 

The 501c3 did not utilize the funds and refunded in it back to me in 2020. I deducted the gift in 2019, how do I report it reversed in 2020? My concern is making it seem like I and the 501c3 was trying to reduce my tax bill illegally. 

 

Thanks in advance
