6 Digit IRS Pin vs 5 Digit Turbo tax box

I have a 6 digit IRS pin to put into a 5 digit box in Tax.  A communiity post gave the sequence of handling it but I cannot find the various points mentioned which said: ' Go to Federal>Other tax situations>Other Return>Identity Protection> and enter the 6 digit PIN.  There is no tab/menu item that says 'Federal' that I can see.   Turbo tax should ask if you have a 6 digit or 5 digit pin.
