French Tax/TVA forms - Can anyone please help me??

[Daft Doctor]

Hello and thanks in advance for any help offered.  I am a UK resident, buying an off-plan leaseback property with my wife.  It is only at foundation stage at present.  The TVA recovery on the build has been handled by French Accountants.  On Friday 2nd May I received a letter from them, along with 2 copies of form 2031 K, forms 2033 A-G, and 2 copies of form 3517 K.  Their letter was in french, but it said that the forms related to TVA due on the rental income, of which there has been of course none to date.  It also said these forms should be a the french tax office by 30th April, but apart from telling me to cross out their address and put my own in in red, there were no instructions as to how to fill these forms in to reflect the circumstances!!  

I really just need to know what I should put on the forms and where I should put the zero's!  Form 2031 k has options at the top including a TVA option and a 'regime simplifie' option, both of which intuitively I think I should tick, and I presume I am a BIC non professionnels as I have no income from commercial letting.  Do I just put zero's in 8a,b and c??  Do I need to fill in forms 2033 if I have no income??  What on earth do I put on form 3517 and where do I put the zero's??

I may need a specialist accountant for this, but it seems daft when just a few zero's need putting somewhere, and I am concerned as I am already past the submission date.  I thought someone may have been through this before and could maybe advise. Can anyone help me??

Many Thanks
