roth 401k vs roth

Hello- If i contribute to a Roth IRA by way of my employers 401k plan do I still enter yes that I contributed to a Roth IRA? We took advantage of the covid 401k withdrawl and it seems to have put us over the limit for Roth contributions. TT is telling me I can withdraw it but when I called the firm that manages the retirement plan they said there is a difference and it is not a "Roth IRA"  it is ""401K Roth IRA". So should I just not check the box referring to Roth IRA
