I use Free Fillable Forms. https://www.freefilefillableforms.com/#/fd
Of curiosity, why do you think you need to disclose a US bank account? The FBAR is only for foreign accounts.
Thanks so much, that website is much easier than some of the others I've been trying to use. So far, I've completed the 1040, Schedule 1, Schedule 6 and the 2555EZ forms.
I originally mentioned the US and UK accounts because I wasn't sure if the US account was relevant. I've since looked back at my bank accounts and realised I didn't have over 10k USD in any UK accounts at any point during 2018 (my husband had most of the money in his own accounts which I didn't have signature access to). This means I don't need to fill out the 8938 or FBAR documents, correct?
Also, I've been filling in the documentation with the information that I had earned $13000 USD in 2018. How accurate does this number need to be? I estimated that I had been working for 1/3rd of the year (starting my job in September) and took 1/3rd of my salary then converted to USD using the exchange rate for Dec 31st 2018. I actually started work a few weeks into September, so my estimate will be slightly over. Considering the variable exchange rate could cause the discrepancy, is it fine that the amount may be 1-2000USD off?
