Urgently time to get another C drive.
The notes from the display indicate that smart shows very little useful life left.
120gb is WAAY too small for a C drive.
You may already have noticed slower performance.
The easiest way to change out the ssd is to buy a Samsung 870 EVO.
240gb is about $50.
500gb is about $53 aas a black friday deal:

1tb is about $100.
Install the new ssd.
Download samsung magician and run the ssd migration app to move your C drive to the new ssd.
The original will remain unchanged.
The process is lengthy, perhaps 2/3 hours.
When done, shut down and remove the original drive.
Your next boot will use the new drive with added space.
Keep the original as a backup or repurpose it later as added storage.
