I had to write the household size with a pen where the 1 is

Did you write over it?

I crossed the 1 and wrote the number in the same box

That field is automatically filled with Javascript. you fill out the other blank fields and the household size is calculated automatically.

@Zaki exactly so, it's automatic, that mean Kira didn't answer all the questions above.

mine wasn’t authentic it wasn’t adding it was 1

Maybe Javascript (JS) is turned off in your pdf viewer software? I occasionally turn JS off to add things that are not allowed like "N/A", but when JS is turned off the automatic fields will not work, so I would turn it back on for those automatic fields.

I answered the questions and it still shows one.

@Zaki I will check with my JavaScript. thank you.

@E K thank you for your feedback. i will check my JavaScript and if that doesn’t work. i will try crossing the one out as you did.
