In your sentence, "the amount of" should be omitted. You could include it, but then the preposition should be in, not "for". That is, either of these sentences would be correct: I have issued a check for $1000.
I have issued a check in the amount of $1000.
We weren't given context, Ws, and the issuer wasn't identified. Over here, while I personally don't "issue" checks (I just write them), it would be perfectly normal to use issue to refer to a check written by a business.
