Does TCS ask for Form 26AS or AIS during background verification

Does TCS ask for Form 26AS or AIS during background verification, and for how many years? I have a TDS entry from a company I worked at for only 20 days about 5 years ago (AY 2020–21), but I never showed that experience anywhere and there is no PF history. Will this cause any issue during TCS BGV? I have submitted BGV documents without mentioning this.
