Actually, you are in a good position to get this cleared up. For purposes of incorporating with the Sec. of State, you can select a date from the date of filing up to 90 days thereafter. But, it appears you have already incorporated, so you will simply need to pay any annual license fees that the Secretary of State imposes.
The Master Business License needs to be completed by the time you begin doing business. So, you should complete your application for a license by the time you begin performing a business function (selling a product, performing services, etc.).
If you have concerns about managing your business, a business attorney might be able to help. Best of luck.
You can put in today's date, the date you incorporated, or an estimated startup date. Don't worry about administrative dissolution. If the Sec of State contemplates doing that it will send you a notice and give you sufficient time to corredt whatever problem caused the notice.
