Ilr appointment next week with tax credit overpayment

[cb13]

I have my appointment slated for next week Wednesday @cardiff peo but have some question to solve.i been on spouse visa since sept 2011 and being living together with my British partner,we have two kids both British but my wife was claiming tax credit as single mum for the years ignorant of the rules that says we have to claim jointly.i am self employed get paid by cash from client.my question is as follows
1)do you think the single tax credit claim will have negative impact on us?though we have informed the hmrc about this and they have stopped the single claim and asked to apply as couple which we have done but still expecting the outcome
2)we received a letter from hmrc saying my wife got overpayment due to late declaration of being living with a partner,so do you think this will make our case not straight forward?
3)what should I put on the form where it asks about if we receive tax credit or not?as the tax credit is stopped for now?
4)do you think I can apply without receiving the tax credit notice yet?
5)can I still use peo for my application as I doubt if my case is straight forward?


I will be grateful if you genius can reply to my questions ASAP
