I have sent my taxes in about 3 months ago and still haven’t got nothing

Due to the pandemic the IRS processing of many tax returns has been limited.

Go to this IRS website for information -  https://www.irs.gov/newsroom/irs-operations-during-covid-19-mission-critical-functions-continue

To check the status of an e-filed return, open up your desktop product or log into your TurboTax Online Account. You can find your status within the TurboTax product.
If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
See this IRS website for federal tax refund FAQ's - https://www.irs.gov/refunds/tax-season-refund-frequently-asked-questions

Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday
When calling the IRS do NOT choose the first option re: "Refund", or it will send you to an automated phone line.
So after first choosing your language, then do NOT choose Option 1 (refund info). Choose option 2 for "personal income tax" instead.
Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions."
- When it asks you to enter your SSN or EIN to access your account information, don't enter anything.
- After it asks twice, you will get another menu.

Press 2 for personal or individual tax questions.
Then press 4 for all other inquiries
It should then transfer you to an agent.

If by "sent in" you mean you mailed it, expect a long wait.  Mailed returns have piled up in trailers for months during the pandemic.  The IRS is just starting to dig through all the mail.  All you can do is watch the IRS site to see if your envelope finally made it out of the pile and into processing.
