You must xtset your data before you can use the other xt commands. xtset panelvar declares the data in memory to be a panel in which the order of observations For xtlogit, pa, correlation structures other than exchangeable and independent require that a time variable also be specified. Use xtset; see [XT] xtset. Manual for Stata Release 17.
