Explanation

When describing how long an action has continued, use 'for' with a duration. 'I have been working here for 2 years' indicates the length of time the action has been happening. 'Since' would be used with a specific starting point (since 2020), 'from' indicates origin, and 'by' indicates deadline. The present perfect continuous tense requires 'for' with duration expressions.
