Thanks, adzino. I'm using an Electrum wallet. When I open it, I see the wallet name followed by three characters in [square brackets] but I'm totally lost as to where to look for the address.

EDIT: I looked at the "receive" tab, but didn't see anything labeled "address". However, if I look at addresses, I see a list of perhaps 20 "receiving" addresses (the word highlighted in green) followed by a list of perhaps 10 "change" addresses (the word highlighted in yellow). Should I use any one of those "receiving" addresses?

Make sure you have full control of these addresses before you deposit and make sure that you downloaded it from legit source(Electrum.org)

To make sure that you are using the legit one you can follow this method below on how to verify the Electrum you currently using(You should do this first for best practices and to make sure that you are not using the fake one).
- How to verify Electrum (for Windows, Linux and Mac)
- How to Verify Your Electrum Wallet on Windows

Now, if it's verified as legit then go to the next step to check if you have full control of your wallet.
It shouldn't be show something like this below

But if it show something like this below then you should have full control of this wallet.

Since, you mention 3 characters under the aquare brackets you might be using a 2FA wallet? It looks like this below.

You shouldn't be worry you have full control of your wallet.

For next suggestion to verify is to use the backup seed and verify if you are using the same addresses generated from recent wallet.
Use this under file below "New/Restore"

Then use the backup seed you must be choose

Then next after that, choose this.

Paste the backup seed then click the next.
Then it will show you two option if you keep or disable the 2FA. If you already have the secret key backup you must be choose the "keep" but if you don't have a backup choose "disable"(Take note if choose disable I don't know if it will still show you the correct addresses that you previously created).
