I reached out to TurboTax
They have responded today:
Hi, I understand that you initially tried to file with T5 on your return and decided to remove it.
There should be an update before this week ends for T5 slips that are causing the locked forms. If you haven't tried filing again, I ask that you please try and check if it will work for you.
For submitting a tax adjustment which I'm assuming you mean making changes to your tax return after filing, there is no payment to use ReFILE or any of the other options for adjusting your return on this page: https://bit.ly/3QMsltl
*** So the good news is, if you removed your T5… once it's functioning properly, you can submit an adjustment request without having to pay extra.
