iPhone SE, iOS 14
Reset it again and try again, as a last test. Failing that, contact Apple using the Get Support link in the upper right, and discuss your options and alternatives. A failing display or digitizer can fail to register or mis-register touch, for instance. (Look at the display while you tap the passcode, and make sure the taps register correctly.)
