Amex Blue Cash Everyday question

I have recently got the Blue Cash Everyday card and got a "Get $200 statement credit once you have spent $2000 or more in 6 months" offer and I applied with it. I am currently at around $1000 in the first month, but currently have a "plan it" plan and I was wondering... Once I do spend the $2000 for that $200 Statement credit would it be used on my "plan it" or would it be something separate? My plan it is $400 that will be split up between 12 months because my parents needed a new washer and they are helping me pay it off between those months, so I was wondering if those $200 in statement not go into that plan and it and be used on my things?
