A 1NT overcall is almost the same as a 1NT opening. The range is increased to 15-18, but the main difference is that you must have the opponent's suit adequately stopped. Here you certainly have the stopper so you bid 1NT. Partner responds 2.

And the responses are the same also. Partner's 2 bid is a signoff bid, often called a "drop dead" bid. So even though you really like the s you pass.
