I got IRS Notice CP321D that says when I filled out my 2023 tax return I didn't check the box that says someone else can claim me as a dependent and that someone did claim me (someone else did claim me). But I on the printout of my TurboTax 1040 it clearly shows the box checked "Some can claim: You as a dependent". IRS wants me to "fix your tax return by filling out Form 1040-X". But there is nothing to fix and no information on the notice of what to do. Any advice would be appreciated.
