What should I do if I forgot to submit a W2 form for my 19-year-old daughter and two 1099Rs for my wife when I filed my tax return. please!

You can not enter your daughters W2 on your return.  She might need to file her own return for it.  More on that later.

Then to fix your return.  You cannot change or add anything on the return that you e-filed.  It is too late, just like when you put an envelope in a US mailbox

Now you have to wait until the IRS either rejects or accepts your return. If your return is rejected, you will be able to go into your account and add or change it and resend it.

If the IRS accepts your return, then you have to wait until it has been fully processed and you have received your refund or paid the tax due. THEN you can prepare an amended tax return 1040X and mail it in. You cannot e-file an amended return.  Meanwhile, DO NOT change anything on your return until you start the amended return. If you did change or add the missing info then take it out and put your return back to the way it was when you first filed it.

How old is your daughter?  Is she a full time student?  

They don't have to file if they only have W2 income under 12,200 but can file to get back any withholding taken out in boxes 2 or 17.  But you don't get boxes 4 or 6 back.

To file a separate return for a dependent you need to set up a new account separate from the parents.  Online is only good for one return per account.  You can use the same email address for 5 accounts.  You can probably use the Free Edition or the Free File website

Be sure on the dependent return you check the box that says you can be claimed on someone else’s return.  If your only income is W2 and under 12,200 you do not have to file a return except to get back any withholding taken out.
