Here's something I ran across the other day. In the instructions for IRS Form 5329, Additional Taxes on Qualified Plans, Part III—Additional Tax on Excess Contributions to Traditional IRAs, there are following hopeful sounding tidbits, which might be what you're talking about:
"If the excess contribution to your traditional IRA for the year included a rollover and the excess occurred because the information the plan was required to give you was incorrect, increase the contribution limit amount for the year shown in the table above by the amount of the excess that is due to the incorrect information."
Then under line 15:
"You can withdraw some or all of your excess contributions for 2021 and they will be treated as not having been contributed if:
• You make the withdrawal by the due date, including extensions, of your 2021 tax return;
• You don’t claim a traditional IRA deduction for the withdrawn contributions; and
• You withdraw any earnings on the withdrawn contributions and include the earnings in gross income (see the Instructions for Form 8606 for details)."
