How do I avoid paying a penalty on an $185,000 Roth IRA distribution we received a 1099-R for. It was a short term loan to our son and was paid back in less than 60 days

We were told by Fidelity that we could withdraw money from our Roth IRA for a short term loan for our son as long as it was deposited within 60 days back into the account.  We did that.  We received a 1099-R for $185,000 today.  My husband is 66.  It is listed under Gross Distribution.
