"later" in hangul vs. "to be"

[Geri19571222]

itt da with "tt" as ssang sheut at the bottom means "to be" (I cannot toggle between English and Korean; it messes up my computer)

itt da goh meaning "later" is not in the dictionary.

A)I am confused about the difference.

B) what is the Korean spelling for "later"; is a jeut used or sang sheut at the bottom of the first syllable?
Can you send a response to my email; I can easily receive the answer.
