Roth IRA recharacterization and backdoor conversion

It looks like I'm going to have to re-characterize all of my 2020 maximum Roth IRA contributions to Traditional IRA due to exceeding income limits. As soon as I do that, is it possible for me to take advantage of the Traditional IRA to Roth IRA backdoor conversion for 2020, for the maximum amount?

Do you have any other traditional IRAs?

I don't have other traditional IRA(s).

Then I don't see why you couldn't convert the IRA to a ROTH without too much difficulty, though completing it all in 2020 may not be possible at this late date.
