TurboTax will automatically generate an IRS form 8453 if you are e-filing your tax return and you are required to mail the IRS supporting documents.

We commonly see IRS form 1099-B brokerage statements mailed with IRS form 8453.

The IRS is looking for the form to be mailed within three business days of your tax return being accepted by the IRS. The mailing instructions generated by TurboTax will provide a mailing address.

For what purpose are you needing IRS form 8453?

if you're using Form 8453, every line entry on Form 8949 with multiple transactions requires code M, which produces Form 8453. Only Schedule D entries on lines 1Aa and 8A do not require details of these trades to be sent to the IRS.
