The Gaza MoH absolutely does incorporate those web form submissions into its numbers. They've said so themselves on several occasions.
The 11,069 number is from [1], or [2] is from a more neutral source:
> Gaza's health ministry has removed 1,852 people from its official list of war fatalities since October, after finding that some had died of natural causes or were alive but had been imprisoned. [...] Almost all of the names removed (97%) had initially been submitted through an online form which allows families to record the deaths of loved ones where the body is missing.

The fact remains, the 75k number is roughly agreed on by everyone prior to Israel destroying so much infrastructure and killing so many people that they stopped being able to count. Israel continues to kill people, that number isn't being counted anywhere. We'll probably never no for sure how many Palestinians have been killed in this genocide.
One thing is for absolute certain though, the population of Gaza has not gone up.
