Your 2022 Roth IRA contribution limit is based on your 2022 MAGI, which you say will be around $90,000.
If you have already contributed another $5,000 for 2022, that complicates things a bit. You'll either have to obtain a return of $4,000 (only $3,000 if you are age 50 or over) of that contribution to make room to apply the $5,000 excess as part of your 2022 contribution so that the total treated as your 2022 contribution does not exceed the annual limit for your age. The deadline to obtain a return of part of your 2022 contribution is the due date of your tax return, including extensions, but reporting would be far much easier if you obtain that return of contribution before the end of 2022. Otherwise you could simply make a regular distribution of $4,000 ($3000 if age 50 or over) by December 31, 2022. (If your Roth IRA has lost value since contributing the new $5,000 for 2022, a return of a portion of that contribution would be the better choice since the adjusted amount distributed would be less than the amount being returned, otherwise it would be better to take the regular distribution.).
Separately you must file 2021 Form 5329 Part IV to report the excess $5,000 Roth IRA contribution for 2021 and pay the $300 penalty if you have not already done so. There is no good reason to delay filing this since it's separate from your 2022 tax return. Line 24 of this 2021 Form 5329 carries forward to line 18 of your 2022 Form 5329.
