If these were truly distributions from traditional IRAs and the Forms 1099-R have the IRA/SEP/SIMPLE box marked, you've violated the one-rollover-per-12-months rule. Only the first of these distributions to be rolled over was permitted to be rolled over. Amounts deposited as rollover contributions that are in violation of the one-rollover-per-12-months rule are excess contributions to the traditional IRA that are subject to penalty.
If the money was properly moved trustee-to-trustee, the transfer is neither a distribution nor a rollover and should not have been reported on a Form 1099-R.
