Narrative:

Working ZZZ center I believe; at FL380; was given instructions to cross zzzzz at FL290. Set 500 FPM descent in FMS; with intention of verifying and adjusting once stabilized in descent. Person a came from cabin and began conversation at cockpit; distracting me from my intended task; and I did not see that we were not going to make 29;000 at zzzzz until just before crossing; increased rate of descent in attempt to make [the] restriction. Estimate missing crossing by 500 feet or possibly more; as at approximately the same time; center called and gave us descent to FL240; so we continued our descent. No mention was made by ATC of any conflict nor any questioning as to what our status for making the restriction was. This was our first trip in the aircraft in almost three months; due to covid-19 pandemic issues; and also the first time we had worked as a crew in almost three months. Recent experience was certainly a factor; but not an excuse. I am extremely disappointed with myself for not staying better focused on my immediate task; and counseled the first officer on duty to monitor when pilot not flying.suggest all crews redouble efforts and vigilance in these trying times as we are all working in unfamiliar situations now with the pressures put on us by the pandemic. Fortunately at this early stage of things moving back toward some semblance of normal; there was probably not a great possibility of a traffic conflict. That will change in the coming days; and even though we may not personally make any more mistakes as these; there will be other crews coming back to flying from furloughs; etc. That still need to get their game back. Looking out for ourselves and the other guys and gals even more than we did before will be the new normal for some time.
