Refund Processing Fees Effecting Return

Hello So I've used my Federal Refund to pay for my fees on Turbotax. And I know my refund should come within 21 days does this take longer now, I just found out this information less than 5 minutes ago since I've used the Turbotax option to pay for my Efile, instead of using my Debt Card. Wow! this is new informative information I didnt know it can hold up your refund???  So this can take a week or 2 am I correct or what does this mean?
