Mistakenly deposit to Roth IRA from my checking account

I supposed to roll over my Roth 401k to a newly opened Roth IRA, but I transferred the money from my regular checking account. The transaction is made within a week and is labelled as rollover according to the Vanguard rep. Now I have 26k in the Roth 401k and 26k in the Roth IRA.  Can I just transfer the money back to my checking account from the Roth IRA without any tax penalty? Or what else so I do? Thanks.
