If you timely filed your return without withdrawing the excess contributions, you can still make the withdrawal no later than 6 months after the due date of your tax return, excluding extensions. If you do, file an amended return with “Filed pursuant to section 301.9100-2” entered at the top. Report any related earnings for 2021 on the amended return and include an explanation of the withdrawal. Make any other necessary changes on the amended return (for example, if you reported the contributions as excess contributions on your original return, include an amended Form 5329 reflecting that the withdrawn contributions are no longer treated as having been contributed).

tell Turbotax you withdrew it by 4/18/2022

make sure to include any earnings. 

you will need to paper file - see bold above. 

since apparently there was no 5329 with the original. there won't be one for the amended. just include a full explanation. 

tell Turbotax you withdrew it by 4/18/2022

Yes

make sure to include any earnings. 

I think you have to make a "substitute 1099-R" to report the earnings from the withdrawal, if there are any earnings.  The earnings will be subject to regular income tax plus a 10% penalty for early withdrawal unless you are over age 59-1/2 and the Roth IRA was open at least 5 years.  Someone else may have more exact advise on how to report the earnings @macuser_22 @VolvoGirl

agreed

If you originally filed by telling Turbotax that you would remove the excess, then there was no 5329 generated therefore nothing to remove.  And since you already told turbotax you planned to remove the excess by April 15, that by itself won't trigger an amendment (Turbotax will tell you there is nothing to change.)  The change that will allow Turbotax to recognize an amended return is needed is the addition of the taxable earnings.

If there are no taxable earnings because the Roth IRA lost money, then I don't know how you can file.  What you technically need to do is to send the exact same tax return again, plus a form 1040-X with no changes, with the bold statement at top, and a written explanation.  But turbotax won't generate a 1040-X if there are no changes. You may need to print one out and fill it in by hand.
