If Function - Tracking Daily Employee Attendance

I am creating a spreadsheet that tracks daily employee attendance.

The title for the E Column is, "Received On Time?"

In the next column, I want to enter a formula that does the below:

If I enter Y, the cell reads "N/A"
If I enter N, the cell reads "ENTER TIME"
If the cell is BLANK, the cell should read "NOT RECEIVED"

So far, I have entered the below function in a cell in my excel spreadsheet, which worked perfectly:

=IF(E3="Y","N/A")

I also want to add in this same cell:

=IF(E3="N","ENTER TIME") AND =IF(E3="BLANK","NOT RECEIVED")
