I used TurboTax online to amend 2021 return. It's been over 3 weeks and no information on IRS page. How do I access amended return and make sure it's been filed?

It is not clear on my online TurboTax account that the amended return has been filed. How do i confirm that it has when the IRS has no information on it yet? They say it takes up to 3 weeks to show up in their system and it's been over 3 weeks. Also, how do i access the actual amended return on my TurboTax online account? It only shows the original, non-amended return.
