Where to enter rolled over 401K reported incorrectly on a 1042S

Last year, I rolled over an old 401K into my current employers 401K. The financial institution reported that on a 1042S, saying they didn't have required documentation saying I was a US citizen, despite having my SSN, and a dated email showing that I had emailed documents before the rollover occurred. How do I record the 1042S and the fact it was rolled over into another 401K?

If done by direct rollover, the transaction is nontaxable and not subject to withholding, so it's unclear to me why reporting on Form 1042-S would have been necessary.

I would probably submit a substitute Form 1099-R with which you can supply explanation. Assuming a direct rollover, the code for Form 1099-R box 7 is G and the taxable amount is zero. Unless something has changed to allow a tax return with a substitute Form 1099-R to be e-filed, doing so would require printing an mailing your tax return.
