I am bogged up with work right now, so I won't be able to help you.

Detailed answer

Up is the most appropriate word to be used at this moment that gives the sentence a special meaning.

• The word up makes the sentence a grammatically appropriate word.
• The word up is usually used to denote a direction but in this sentence, it is used to denote a lot of work.
• The sentence now conveys that the person will not be able to help as he had a lot of work.
