Capital gains account opened last year (2016), but amount is not yet utilised. which itr form to use now?

Hi,

Last year (2016 September) my mom had got some capital gains from sale of house. The amount was deposited in capital gains account in nationalised bank. The amount has not been utilised and will be used this year for purchase of house. For assessment year 2017-18, ITR 2 was filled.

Now my question is for the year 2018-19, should we file ITR 1, since there is no income apart from salary this year? Or since the capital gains account is still live and amount not utilised should we file ITR 2?
