Where is my Refund

I submitted my return and was accepted on 1/29/2024 using Turbo Tax Deluxe. I took the standard deduction so I am confident there is no audit chances.  I still have not received my refund. I did my sons taxes the same day and he has already received his refund. When I check the IRS.gov website it shows as being received but does not give a reason for the delay. There is no reason why it is taking so long and with scammers I am concerned. How can I check to find out why such a long delay.
