Missing Tax Documents

I've been working since 2014 and have unfortunately no idea where my W-2 or tax documents have been. I have been filing my taxes every year of course and have been paying my taxes timely, but I have only the past few years of W-2/tax documents handy (around my house). I cannot find the rest.  Will this be an issue for me later down the road?  Any negative repercussions?

 

Specifically, after I retire and qualify for social security , will they give me issues because of the fact that I cannot find the above documents?
