GSTR 1 for the month of Mar 2018

Any notification about GST 2 and RCM?

My questions are
a) How to calculate turn over?
b) Can I take benefit of presumptive tax clause?

Do I have to again take a letter of undertaking from April 2018 or the previous one is valid ?

An assesse received the letter depicting Temporary Permission to carry out furniture work
in flat purchased subject to inter alia terms & conditions as below:

That flat is ready for occupation but we (builder from whom flat purchased) is yet to receive
occupation certificate From Municipal Corporation.

Please advise whether upon receipt of such letter, the deduction towards interest paid on
loan for purchase of this property can be claimed in determining the income from
house property

Should we mention details of debtors, creditors and cash detail in Itr 4. If we do not then wat will happen..
