help with UK-USA form US-Individual 2002 Part A

Hi, Part A Your personal details The Service Centre address where your latest tax return was filed and the date your latest tax return was filed Is it about UK or US service center? If it asks for US service enter, I don't have one since I did e-file (electronic filing). Is it ok if I leave it blank? Sincerely, Hui

Hi,
This would be the address of your local/main tax office in USA and needs to be completed.
Thank you.

Hi Hui,
The question " The Service Centre address where your latest tax return was filed and the date your latest tax return was filed", relates to your IRS tax return and not your UK tax return.  (https://assets.publishing.service.gov.uk/media/5de8de99ed915d09d0f7fded/Form_US-individual_2002.pdf) (https://assets.publishing.service.gov.uk/media/6384bc43e90e077898ccb48a/DT_US_Individual_Notes.pdf).
