If the rollovers were to an IRA rather than to another qualified retirement plan like a 401(k), the IRA custodian will issue a Form 5498 reporting the rollover contributions to the IRA by the end of May, but this form is not needed to prepare your tax return. If the rollover was to another qualified retirement plan like a 401(k), the receiving plan will not report anything except to show the transaction on your account statement.
