This is a very common issue and easily fixable. Do not try to dig it out yourself with tweezers or another swab, as this can push it deeper or damage your eardrum. Do not use any ear drops, olive oil, or water, as moisture will cause the cotton to swell, making it much harder to remove. If a portion of the cotton is clearly visible right at the entrance of your ear, a friend can try to gently retrieve it with tweezers. Otherwise, please visit an urgent care clinic or your doctor. A healthcare professional can safely and painlessly extract it in seconds using specialized tools.
