Ah, clear now. Your inputs are telling the HP to calc the PV of a single future amount of 100K, to which the machine responds...

which is indeed 62,092.1323.
But remember that in
this problem you're finding the PV not of a single future amount, but rather of a sequence of multiple, equal amounts (20K, annually, 5 payments, beginning one year hence).
It can be solved pretty quickly mathematically (there's a shortcut formula available when all the future cash flows are the same amount; aka an "annuity"), but to knock it out on your HP, pull out the manual and look up the instructions for calculating annuities.
