One time password filling error on Threatlocker.com

Thanks for providing the page's structure.

I'd like you to try the following:

1. Open your 1Password.
2. Click the PLUS icon and select "Login" from the list of options to create a new login item.
3. Give it a name, then fill in your username and password for this website in the relevant fields.
4. Under the username and password, paste the website's URL into the "website" field.
5. Under the website field, select an empty custom field, click on the three dots menu to the right and change the field from "Text" to "One-time password".
6. In the label of this field, type in txtOtcPass so that would be the field's name.
7. Copy the secret of the 2FA field from your current login item into the one-time password field under the txtOctPass label.
8. Click on "Save" to save your new login item, then test and see if it autofills the page properly.

Here's a screenshot of what the login item should look like while editing it:
