is there central place to see archived w-2?

If you cannot obtain the W-2 from your employer, then for a fee you can get a complete copy of a W-2 from the Social Security Administration - https://faq.ssa.gov/en-us/Topic/article/KA-02501

You can get a free Wage and Income transcript from the IRS - https://www.irs.gov/individuals/get-transcript

It depends. The best place would be to see if you could get copies from your employers for those tax years. You can order transcripts from the IRS and they have the last nine years:

• Tax account transcript - shows basic data such as filing status, taxable income, and payment types. It also shows changes made after you filed your original return. Generally, this transcript is available for the current and nine prior tax years through Individual Online Account, and the current and three prior tax years through Get transcript by mail or by calling 800-908-9946.
• IRS Transcript Types for Individuals and Ways to Order

The IRS doesn't typically keep state data, so if you need it, you will have to contact your state.
