If Appendix No. 4.A does not appear or works incorrectly in the Form 300 declaration for goods imported with VAT paid by the offset method (cabinet No. 3), the reason is most often the absence of the necessary patches (fixes) for this form in the 1C configuration.
What to check
Go to the Administration → Maintenance → Installed Fixes (Patches) section and review the list of installed patches. The presence of exactly 5 patches affects the correct operation of Form 300 and its appendices, including 300.04.A.
If there are no patches, or fewer than five, this is the cause of the issue with the appendix not displaying. You need to update the configuration or install the missing fixes.
How to provide information for verification
For a support specialist to accurately determine what is missing, it is best to take a screenshot of the patches section and send it to support — or simply confirm whether all 5 patches are present there. This will help quickly determine whether the missing updates need to be installed, or whether the problem lies elsewhere.
