No, you don't. You will only need to engrave the information that is located in box 3b. This will be the individuals name, gun trusts name, corporations name or other legal entities name, followed by the city and state from box 3b.
When applying as an individual, whether you are using the ATF Form 1, ATF eForm 1, ATF Form 4 or the ATF Form 5, you aren't required to complete the ATF 5320.23. These questions will be answered on the forms itself or on the eForm 1 application. This means that when you are applying for a tax stamp using the ATF's eForm website the ATF 5320.23 "Choose File" will be greyed out like shown below. This is normal for an individual applicant and nothing to worry about.
The payment is taken by the ATF as soon as you complete the payment screen. This is required in order to submit your application to the ATF. If you applied using the ATF's Form 1 paper application, the same is true. Your $200 tax payment is charged before your ATF Form 1 paper application moves to the next step.
