Sia hardforked early on December to implement a new Difficulty Adjustement Algorithm, so old versions of the client before 1.3.0 are not compatible with the new mined blocks. For that reason, recent transactions can't show up in your wallet.
The latest client can be downloaded, as always, from the official website: https://sia.tech/apps/ To upgrade close Sia completely (click "close" on the system try icon), replace the old installation files with the new ones and open Sia again. More details here: https://siawiki.tech/client/updating_the_interface
As you didn't upgrade before the fork, most probably you will see a blockchain incompatibility error and will need to delete the consensus file. If you find this or any other error after launching the new version, follow this troubleshooting guide: https://blog.sia.tech/troubleshooting-the-recent-hardfork-ca77e0b17f0f
