Where do I enter this unclaimed property amount on my return?

[DavidS127]

It depends on what was reclaimed and how it was reported to you.  Some unclaimed funds will not be taxed, for example, tax-free investments such as municipal bonds, a 401(K), or an IRA.

When interest is paid on the amount of your unclaimed property, it will be reported on Form 1099-INT.  In that situation, the 1099-INT is entered as interest income on your tax return.
