I have another question, on the VAF4A, (1.19) if I have stayed with my now wife at the same place since we got married on 7 April 2018, do I just put that we have, the address of where we were staying, and the dates we have stayed there? Would it be an issue if it isn't the address I normally live in America? We have been staying at a close family friends.
Is this on Appendix 2?
If so, the question is asking if you have 'lived together in a relationship akin to marriage' at any time. This is not 'staying' together, this legally living together in the same country. And it's really only aimed at people applying for the Unmarried Partner visa, where they are not married but they have to show they have legally lived together for 24 consecutive months before applying.
So, if you have only been temporarily staying together at someone else's house, this is not living together, and so your answer to 1.19 is NO.
If you say yes, you need to be able to back it up with evidence that you both lived at the same property, by way of tenancy agreements, utility bills in both names, bank accounts at the same address etc.
