Under the Cares Act for Charitable cash contribution, Can I enter $300 If I donated but have no receipts? or just put $0 since I dont have my receipts?

Is it ok to enter $300 under cash charitable contribution made in 2020 if I don't have any receipts or proof? or should I just leave it $0.00 since I don't have proof ? Thank you

Cash donations have to be receipted or otherwise acknowledged by a recognized charitable organization to be deducted.
