Applying the 2020 excess as part of your 2022 Roth IRA contribution does not involve the investment company. It will be done on your 2022 Form 5329. Line 18 will have the excess carried in from 2021 Form 5329 line 24 and line 19 will have the amount of the excess being applied as a 2022 contribution.
The 6% excess contribution penalty for 2021 will be due with your 2021 tax return. (This assumes that you do not make a return of any of your 2021 Roth IRA contribution to be able to apply the excess as part of your 2021 Roth IRA contribution instead.)
