It's probably a change address used by the wallet. Change addresses are what allows you to not only spend large chunks of Bitcoin at once. Unless your balance has decreased more than you expected it, you should be fine.

I should have received 0.27298966 BTC which is 0.27459522 BTC being sent minus the miner's fee, but there are 0.26861186 BTC in my balance on Bittrex.
Should I contact them?

0.27298966 - 0.26861186 = 0.0043778

The blockchain link you provided shows the net of the transaction was 0.0043778.

I suggest you look at the transactions in electrum, look for a receive address matching that displayed by blockchain.

There is an address is Electrum and it's matching that is displayed by blockchain, but idk what is that address and why that amount was sent to it

It's called a change address. You can learn more here: https://en.bitcoin.it/wiki/Change

I highly suggest trying to learn more about how Bitcoin works, because it will help you from freaking out/making small mistakes.

Thanks for help!

The thing is I have no idea about that address..Bittrex gave me only one address for the TBC, which isn't that one, and the change addresses on my Electrum wallet doesn't include this one.
