How is the information on a transcript in dispute?

"A tax return transcript shows most line items from the tax return that you filed. It also includes items from any accompanying forms and schedules that you filed. It doesn’t reflect any changes you or the IRS made after you filed your original return.

A tax account transcript includes your marital status, the type of return you filed, your adjusted gross income and taxable income. It does include any changes that you or the IRS made to your tax return after you filed it.

You can get your free transcripts immediately online. You can also get them by phone, by mail or by fax within five to 10 days from the time IRS receives your request."
