The Note 29 Ultra does not support 45w charging. If you plug the 45w charger in and compare the time it says it takes to fully charge, it is the same time it says when plugged in with the 25w charger. Same time to charge regardless if you use a Samsung 45w charger or Samaung 25w charger. Times are different when you use the Note 10+.

I think what they are saying is they plugged borh in and it calculated the same amount of time remaining on the Note 20. On the Note 10 it calculated to different times. Only way to tell for sure would be to measure the amperes.

I know this is old but this is one of the first things you get on google when you type in "fastest note 20 ultra 5G charger".
To be clear, the Note 20 Ultra 5G dose NOT support 45W charging. The fastest it supports is 25W, which is what the included charger is.
The only Samsung phones I can find that have confirmed 45W charging are the Note 10+ and S20 Ultra. Not even the S21 Ultra dose 45W, it tops out at 25W as well.
On phones that make use of the 45W chargers you will get a notification saying "Super Fast Charging: 2.0"
Don't feel bad though, tests have shown that the difference between the charging time of the 25W and 45W phones is usually <5 mins difference. Probably why Samsung hasn't bothered supporting it in more than 2 phones.
