Form 2210 page 4, in Schedule AI Part II labeled Annualized Self-Employment Tax, on line 30 "Enter actual wages for the period subject to social security tax," Leave it blank for both the Tax Payer and the Spouse. If you enter $0, that $0 is the root of the issue. Entering a $0 will generate the additional page 4. If you leave the entry blank, it will not print the additional page 4.
I hope this helps.
