The dates that you worked for specific employers are not ever included in your tax returns. The W-2's or 1099NEC's you receive only show what you earned during the whole calendar year. The tax documents do not break it down by months. Employer names are not shown on your tax returns. The names of the employers are on the W-2's issued to you, and are on the worksheets that are part of the pdf of your saved return. Again--only the year you worked will be shown there---you will not find which months you worked.
Social Security can provide a work history that might help you. If you change jobs frequently then you need to keep track of those employers yourself by writing it all down someplace where you will not lose it.
