It doesn't give me the option of choosing a tail. Any tips on fixing that? I have a TI-84 Plus CE

In my math problem, 1.28 isn't the Z score for 90%, it's 1.29 because 1.28 is still under 90 while 1.29 is over it. This makes it more complicated for me because using your method to find the Z score of a probability would get me the wrong answer. Is there any way of seeing a table of score distribution on my TI-84? I see there's one online but I obviously can't use that in the middle of a test
