My Client Wants Me To Send The Money To The Supplier

I'm a graphic designer and I got an email regarding logo and business card design from this client. We have been discussing about the idea for the logo, which was smooth process. He said he sent the money $1980.89 including the 50% of the design fee and the printing supplier cost. I was really suspicious of that so I asked him why I am the one sending the money to them cuz it would typically make more sense for the payment to be handled directly between his business and the printing supplier. And he said the reason for this is that the printing supplier currently has a delivery issue preventing mail from reaching their location.

Eventually, I got a check from him through the Fedex mail and have tried online deposit and the transaction got hold by my bank. I've never encountered this kind of issue, which makes me more suspicious of this, so I searched up on reddit and google if there is anyone who have encountered this situation, but couldn't find.

In conclusion, is this a scam?

Update: I just blocked the "fake" client. Also, since the fake check deposit got hold by the bank, so is there any action that I should take? Should I call the bank to say I got fake check and ask them if there is any way to cancel the transaction?
