N400: found travel information error after submitted online

[indiahelp]

I just submitted N400 form online. I made two errors on my travel history.

1) I realized that I didn't include my 6 day trip to Canada which I took by road.
2) In one of my Europe vacation I did some day trips to Prague but didn't add Czech republic as one of the many countries visited in the same trip. The travel dates in this case is fine.

How can I add this information?

Should I upload a clarifying letter online (place where documents can be uploaded)?
or wait for interview?

Thank you for your help.

At this point, I think you should wait for your interview, but I'm no expert. Good luck.

Do not worry, you can correct application in interview and also update any change in your address, job, new travel and etc, just stay safe and wait for reopening the offices to public.
