If I filed my amended electronically how will I receive my refund

The ONLY way amended return refunds are issued is to a check mailed to the address on the tax return. 

and plan on waiting at least 6 months for it.

@SweetieJean - closer to a YEAR. .... my last amendment in my family for 2020 tax year was submitted in May, 2021 and I received notification TODAY that it was resolved. THIRTEEN MONTHS.

Even during “normal” times it takes about four months for the IRS to process an amended return.  During the pandemic and due to the severe backlog at the IRS it is taking much longer—six months or more for many amended returns.  Do not expect quick results from amending.  When the IRS issues a refund for an amended return it will be by check.  They do not make direct deposits for refunds for amended returns.  You can watch for information here:
