Why did my refund go from "accepted" to "pending" on Turbo? IRS already accepted it & already posted my deposit date on my transcript as well. I'm so confused now!

IRS accepted my refund around January 27th. Since then, TurboTax has shown it as "accepted." I checked my transcript 2 days ago and it finally showed my "refund issue date," which is February 24th. I also chose to do the TurboTax 5 days early payment option where you pay for them to send your refund 5 days earlier than the date the IRS plans to deposit your refund... That would have been yesterday, the 19th, for me, but instead of getting my refund, TurboTax just changed the status of my refund from "accepted" to "pending" & I have no idea why, so I was hoping someone could explain what it could mean.
