'Tilgen' (to repay/to erase) is a formal word that you mainly find in written language, official documents, or an elevated style. It is used less often in everyday conversation.

The contract specifies how the remaining debt is to be repaid.
The difference between the meanings becomes clear through the object. If it is about money, e.g. 'Schulden' (debts) or 'Kredit' (loan), 'tilgen' means to repay. If it is about information, e.g. 'Daten' (data) or 'Eintrag' (entry), it means to delete.
Sie konnte den Kredit schneller tilgen als erwartet.
She was able to repay the loan faster than expected.
In a financial context, 'tilgen' (to repay) is almost always combined with words for monetary debts. Typical examples are: 'Schulden tilgen' (to repay debts), 'einen Kredit tilgen' (to repay a loan), or 'ein Darlehen tilgen' (to repay a loan).

With the new job, he can finally repay his debts.
In the meaning 'löschen' (to delete), 'tilgen' (to erase) is often used for abstract or digital things. Common combinations are: 'Daten tilgen' (to erase data), 'einen Eintrag tilgen' (to erase an entry), 'Spuren tilgen' (to erase traces), or also 'eine Erinnerung tilgen' (to erase a memory).

to extinguish / delete
Löschen is the usual general verb for removing data, entries, or written text. Tilgen also means to remove something, but it sounds more elevated and can emphasize deliberately eliminating something completely. For everyday file operations, löschen is therefore usually the better choice.
