I was told I got a estimated refund for this past Sat 2-22 why haven't received anything?On the Irs website It says I need to wait 24 hrs to get info, Its been longer?

If Where's My Refund reflects your refund has been approved and sent, per the IRS website: https://www.irs.gov/individuals/refund-timing it can take a few days for the funds to show up in your account.

Why does it take so long for the funds to show up in my account?

It takes additional time for refunds to be processed after leaving the IRS, and for financial institutions to accept and deposit them to bank accounts and products like debit cards. Also, many financial institutions do not process payments on weekends or holidays, which can affect when refunds reach taxpayers. For EITC and ACTC filers, the three-day holiday weekends.

The IRS also states you should wait 5 days before contacting them if your refund shows it has been sent on Where's my Refund? and it has not been posted to your account.
