Only the second one is grammatically correct. The essential part of a possessive in Turkish is the suffix that is attached to the noun. This suffix must match the possessor in person (1st, 2nd, or 3rd) and number (singular or plural):
my noun = benim nounUm
your noun = senin nounUn
his/her/its noun = onun nounU
our noun = bizim nounUmUz
your (pl) noun = sizin nounUnUz
their noun = onların nounU
Just a few more things to note: All the vowels which I have capitalized must have vowel harmony with the word they are attached to. And while it is permitted to omit the possessive adjective (benim, senin, etc.), it is never permitted to omit the suffex (-um, -un, etc.).
please help me how to make sentence (subject) have a (noun)
and (sunject)'s (noun) how to make sentences i am confused
This phrase above is not a sentence.
You said if the pronoun is "O", we should add "U". (Or letter ı in this case) So where the s come from? Should it be something like "makarnayı"?
Makarna ends in a vowel and the rules are that for possessive third person, they will add an -s- between the two vowels and not a y. Scroll down here to see the tables: https://www.duolingo.com/skill/tr/Possessives or on this page: https://www.duolingo.com/comment/8612302

We don't know, so both should be accepted as correct.
Macaroni is a specific kind of pasta in English, but "makarna" can be any kind of pasta: spaghetti, rigatoni, etc.
