How does one go about tracking down 401(k)s from previous companies? Is there a more convenient method than trying to get in contact with HR from these past companies? I wouldn't mind paying for a service if it meant less hassle.
In addition to this, I know I've opened a Roth IRA in the past, but do not recall whether that account is still even open, and whether I'm allowed to open a new Roth account. I don't want to accidentally over-deposit. Essentially this is an area of my finances that I don't have managed as well as my bank / personal investment account, and want to begin better managing.
