Self Assessment- ESOP- US to UK

I am an UK employee and recieved stock options from company(ESOPs), the stocks were held in US and I sold them in the previous financial years. During the sale, witholding tax @50% was deducted and the money was remitted to UK account and the capital gains was less than $5000. Please adviise which section in self assessment form is it this one "Did you receive income from UK land and/or property (including income from foreign property) over £1,000? Please check help before selecting" or capital gains section?

Hi Ben Thomas,
Employee Stock Ownership Plans (ESOPs) are company share option plans in the UK.  
Please have a look at the guidance on company share option plan at Tax and Employee Share Schemes.
Thank you.
