Are you looking for something specific?

Because you could just google for instructions.

As far as I know, the TI-83 does not have a single key or a function for the p-value.  It dos have the pdf and cdf of the normal distribution (under 2nd-distr).

You can use the `normalcdf` function to find a desired probability so long as the random variable you're referring to is normally distributed.
|dw:1433040291890:dw|
where the area $p$ under the curve between $a$ and $b$ is obtained with
`normalcdf( a, b, mean, std dev)`

If you're interested in finding tail probabilities, you can also use `normalcdf`. For example:
|dw:1433040518241:dw|
The area $p$ is given by
`normalcdf( k, some large number, mean, std dev )`
