If you are using online TurboTax your fee is the same whether you e-file or print, sign and mail the return. The fee for online TurboTax is for using the software to prepare your tax return---there is not an extra fee to e-file it.
You are not charged a penalty by the IRS or your state if you are getting a refund or if you do not owe tax due. If you owe tax due you were supposed to pay by May 17, 2021, so in that case your penalties and interest began on the filing deadline.
If you use the CD/download software, then there is a $25 e-filing fee to e-file a state return. You can avoid that fee by mailing the state return instead of e-filing the state. If you paid to e-file a state return using the desktop (CD/download) software you can talk to customer support about getting a refund for that $25 fee.
