Assuming no additions are required to your AGI to produce your MAGI for the purpose of a Roth IRA contribution and that your Roth "conversion" was not an In-plan Roth Rollover but instead resulted in a deposit into a Roth IRA as you have implied, your MAGI for this purpose is $170,000 - $50,000 = $120,000 which puts your 2021 MAGI below the threshold where your eligibility to make a Roth IRA contribution begins to phase out for all filing statuses but Married Filing Separately. Based on these assumptions, it seems that you made no excess contribution for 2021.
The distribution that you received should have been an ordinary Roth IRA distribution (code J, T or Q only) because it's far too late to obtain a return of contribution before the due date of your 2021 tax return. Because it has been less than 60 days since this regular distribution was made, you can roll over this distribution back into a Roth IRA as long as you have done any traditional IRA-to-traditional IRA or Roth IRA-to-Roth IRA rollovers in the one-year period ending on the day before you received this distribution that you would be rolling over.
The distribution and rollover would be reportable on your 2024 tax return, nothing about it or any excess contribution on your 2021, 2022 or 2023 tax returns.
