Credit Karma Refund

I filed on 3/26 and was accepted on 3/28. Turbo tax and my IRS transcripts state that today is my deposit day but I haven't received a deposit yet. I did get my state refund in the middle of the day from what I remember, so it could happen in the same way. Just wondering, what time others received there's and/or if there was an additional delay in receiving it to your Credit Karma account. I've been planning to use mine for car repairs and the repairs were completed today... I'm in California, by the way - in case anyone has time specifics for deposits. Thanks!
