I failed to file my 1099B on my 2022 tax return. Can I file that now using Turbo Tax?
Yes, if you filed your 2022 return with TurboTax then you can amend it using TurboTax.
See the following TurboTax help article to get started:
How do I amend my federal tax return for a prior year?
It is wise to amend.
I'd also like to ask if it would be wise to amend the return? Does the IRS actually go back to previous years looking for things?
