Please advice me for my Naturalisation application

[batman62789]

Hi all

I recently applied for Naturalisation by online, selected the option of nationality document return service
i have two questions
1) By filling the application i missed one letter from my name and made the successful payment as well
really confused what to do?????
2) I mentioned as a self- employed year 2017/2018 but i recently registered to HMRC and i don't have UTR number and self-assessment summary
They are asking for other supporting documents for self-employed applicants which is recent tax return or self-assessment, Which i don't have at the moment

I am really worried will it affect my application, Experts can advise me really much appreciated who are reading this thread.
Thanks
