No i think i downloaded it from Electrum's website

Yes it is says it's verified so i guess that's fully synced? I also just installed the latest version of electrum and it shows the same in my wallet. I am also afraid someone got into the wallet. I didn't even turn on this laptop since 2018 and the 12 words and my password are written on paper, not on the laptop.  Bummer.

Hi, i'm a noob but purchased bitcoins in 2013. Last time i did transactions (mostly just buying and selling bitcoins) was in 2018 and didn't sign in into Electrum ever since.
Now i opened my wallet again and see some transactions, and the last one shows a sale and now a bitcoin balance of zero! I'm positive i didn't sell the btc because i don't see a pay out on my bank account around the same date that this transaction took place.
Did i get robbed or is there another way i can restore my balance???  please help!
