How to start Unclaimed tax return

[DoninGA]

The IRS will send you a CP237A if the tax refund check they sent you was never deposited. If you received this notice, call 1-800-829-0115 to claim your refund. In most cases, you will get your refund within 30 days of contacting the IRS.

What do you mean by "unclaimed" tax return?  Are you referring to whether you are claimed as a dependent by someone else---or that you cannot be claimed as a dependent?   If that is what you are asking about, in MY INFO you are asked if someone else can claim you as a dependent---you either answer YES or NO.
