Will paying from return delay the time it will take receive my refund

Refund processing won't slow down or speed up your tax refund.

It will post to my account just as fast as if I payed with credit card?

You won't see it on your bank account. The amount will be taken right out of your expected refund amount. There is a fee for that service though.  So if you want to avoid the fee, you can just pay with credit card.

Right.... I just didn't know if it would take longer to see my return.... if there was extra processing time for turbo tax to deduct the fee then send the rest to my account

No it will not make a difference on how long it will take you to receive your refund.
