My 401k plan used to send out yearly statements showing the various amounts contributed.
With some plans, they transitioned to electronic records where you logged into your online account to see & download those amounts.
If you've since, rolled over those amounts to other accounts, and no longer have an online account with that 401k provider.....then it may be difficult to impossible to recover the value of those matching contributions.
You could check your paper files to see if you have any paperwork about that 401k plan that show what % the employer matched...or if you know anyone still working at that employer, ask them to check to see what the match is. IF you get that, you might be able to approximate what the match $$ was by getting out your old W-2 forms from that employer to see what amounts you contributed each year, and calculating what the employer match might have been from those $$ amounts.....thought he calculation wouldn't be straightforward.......it would give you an idea of what the employer provided each year.
